Description

Novel fixed bed adsorption tower
Technical Field
The invention relates to the technical field of coal gas dust removal and purification, in particular to a novel fixed bed adsorption tower.
Background
The coal gas production refers to a process of introducing air, water vapor or hydrogen and the like into coal or coal coke under the conditions of high temperature and high pressure to prepare combustible gas, and is an important way and means for cleanly utilizing coal resources. The application of the coal gasification combined cycle power generation system promotes the development of the coal gas technology. However, high-temperature coal gas produced by coal gas production contains a large amount of dust, which not only reduces the quality of the coal gas, but also causes abrasion to gas turbine blades, and reduces the service life and the working efficiency of the gas turbine. Therefore, it is necessary to perform dust removal and purification treatment on the high-temperature coal gas produced from coal gas. The wet purification process is usually adopted to carry out dust removal treatment on the high-temperature coal gas. The main steps are that the high temperature dust-containing coal gas enters into the double vertical pipes through the partition water seal. In the double vertical pipes, most of dust and impurities in the coal gas are removed by the countercurrent spraying of cooling water and the coal gas. Then the coal gas is led into a washing tower, and the coal gas is further purified and cooled by cooling water, and the temperature of the clean coal gas basically reaches the normal temperature. The treated coal gas enters a drop catcher to catch liquid drops carried in the coal gas, and finally the gas is conveyed to a gas using point for use by a pressurizing machine according to the required pressure.
The wet purification process mainly has the defects that the temperature of purified coal gas is low, the requirement on the temperature of the fuel gas in a coal gasification combined cycle power generation system is difficult to meet, and the energy utilization efficiency is reduced; the process is complex, the coal gas is purified by water treatment, the sewage needs to be treated, and the investment cost is high; the filtering material is not easy to clean, and the purification efficiency is low. Therefore, much research is currently focused on how to remove dust from high-temperature coal gas by using a dry purification process. However, the temperature of the produced coal gas at the outlet of the gasification furnace can reach 800 ℃ at most, and the common bag type dust collector and the electrostatic dust collector can not meet the use requirements easily. Although the prior art also has a dry dust removal device for filtering and purifying, the devices have the defects of various process steps, complex structure, poor sealing property, low purification rate, short service life, troublesome replacement of failed parts and the like.
